Actually, this is about a different section of the documentation. But it might still be best to update /Doc/reference/expressions.rst first in Issue 12067, and then sort out /Doc/library/stdtypes.rst to match.

Why do we need a dedicated section in Built-in Types about Comparisons? I think it might make more sense to just document how comparisons work separately for each type (Numeric, Sequence, Text, etc), if this is not already done.
